PIPE-.JOINTEFL SPECIFICATION forming part of Letters Patent No. 691,678, dated January 21, 1902.

Application illed August 12, 1901. Serial No. 71,832. (No model.)

To @ZZ whom t may concern.:

Be it known that I, CLEoPHAs VANDALma citizen of the United States, residing at Eveleth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Pipe-Jointers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in pipe-jointers, and more particularly to that molten metal used for joining purposes.

It consists of a flexible strip adapted to en-v circle the end of a pipe-joint, means carried by said strip for drawing the ends thereof together, and means for directing the flow of molten metal into the pipe-joint.

It also consists of certain other novel constructions, combinations, and arrangements of parts, as Willbe hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a top plan view of the pipe-jointer embodying the features of the present invention and illustrated in position upon a pipejoint. Fig. 2 represents a view in side elevation of the said jointer detached, and Fig. 3 represents a transverse section taken on line 3 3 of Fig. 2.

In uniting the joints of pipes, particularly those intended to be gas or water tight, it has been found necessary to provide telescoping ends forming joints adapted to be iilled with solder or other material for protecting the union of the parts and at the same time resisting the pressure of the contained fluid, and in order to facilitate the application of the solder or other material I provide, as seen in the accompanying drawings, a preferably iiexible strip, as 1, which is usually made square in cross-section. The ends of strip l are preferably beveled, as seen at 2 2, and one of t-he endsis provided with a plate, as 3, which is rigidly secured thereto and extends a considerable distance beyond the same for purposes hereinafter described. A preferably rigid member 4 is secured to the strip 1, longitudinally thereof, by any preferred retaining means, as 5 5, and one end of said member is provided with an eye, as 6,

site end from that carrying member 4. Said plate 3 and said rack 10 may, if desired, be integral, said plate forming aflange at one end of rack 10 and extending beyond the same. In operation stripl is caused to encircle the smaller'end of a pipe-joint, as shown at 12 in Fig. l, the flat face of said strip being brought against and fits snugly the enlarged or shouldered end, as 13, of the joint of pipe to be secured to joint 127 the side of link 7 next to said shoulder moving in cut-away portions, as 14 and 15, in the said segmental rack and eye, respectively, whereby the said side of link 7 moves in the same plane as the face of strip 1, thereby permitting a very close tbetween said strip and shoulder 13. It will be apparent that these cut-away portions 14 and 15 serve another valuable purpose in limiting the pivotal movement ol said link 7. The ends of strip 1 when in the position described may be caused to approach each other until the teeth of ratchet 8 engage those of ratchet 10, and a downward pressure upon the handle 9 will then bring the said ends as close together as the length of strip 1 will permit, plate 3 having its free ends extended past the end of strip 1, the plate thereby forming a dam for the molten metal to be applied between shoulder 13 and the end ofjoint 12, the said shoulder forming the dam on the other face of strip 1. The parts being in the position described, melted solder or other j oin. ing material is poured into the funnel-shaped opening 16 and is guided by strip 1 about the entire circumference of the end of joint 12 and produces a hermetical seal between the parts. An upward movement of handle 9 will then disengage rack 8 from rack 10 and leave the strip 1 free to be removed from joint 12 for repeating the operation on the next succeeding joint.

Having now described my invention, what IOO I claim as new, and desire to secure by Letters Patent, is-

l. A pipe-jointer, comprising in its construction a flexible strip, a rack carried by one end thereof, a link carried by the opposite end thereof, means pivotally secured to the free end of said link, adapted to engage said rack for moving the ends of said strip toward each other, and a plate carried by one end of the said strip at one side thereof and adapted to extend beyond the other end of said strip for serving as a dam for guiding joining material poured between the ends of said strip, substantially as described.

2. A pipe-jonter, comprising in its construction a strip of flexible material, a member extending longitudinally thereof and seculed thereto, an eye formed in said member, a link carried by said eye, a cam carried by the free end of said link, a segmental rack formed upon the face of said cam, a weighted handle carried by the said cam, a rack formed upon said strip at the opposite end to that carrying the eye member adapted to be engaged by the rack of said cam, whereby operation oi' said weighted handle is adapted to cause the ends of said strip to approach each other, and means for guiding joining material passed between the said ends, substantially as described.

3. In a pipe-jointer, the combination with the shouldered end ot' a pipe of a strip of material adapted to encircle the end of a joint of pipe inserted wit-hin said shouldered portion,

a link pivotally carried by one end of the said i strip, a rack carried by the opposite end thereof, a segmental rack pivotally carried by the free end of said link and adapted to engage the said firstmentioned rack and when swung on its pivot is designed to cause the ends of said strip to approach each other, and a plate carried by one end of said strip and adapted to extend beyond the other end thereof for forming a dam against the escape of joining material passed between the ends of said strip, the said strip tting snugly against said shoulder, whereby the shoulder is adapted to form a dam on the opposite face of said strip to that carrying the platc,thereloy directing said join# ing material about the under face of Said shoulder for producing ahermetical seal, sub stantially as described.

4. A pipe-jointer, comprising in its construction a strip of flexible material, an eye formed upon one end thereof, provided with a cut-away portion forming a shoulder, a link pivotally secured within said eye and having its movement limited by said shoulder, a cam pivotally carried by the free end of said link and formed with shouldered portions adapted to limit the movement thereof, the shoulders of said cam being ot' substantially the same depth as those of the said eye, whereby the arm of said link upon the shouldered face of the eye and cam is designed to move in the vertical plane of the inner face of said strip, means carried by said cam adapted to engage the free end of said strip for causing the ends thereof to approach each other, and means for directing the iow of molten metal between the said ends, substantially as described.

In testimony whereof l hereunto affix my signature in presence of two witnesses.
